安卓JUnit测试没有运行

Question

问题不是测试失败，而是他们根本不运行。 也就是说，控制台告诉我他们跑了，但我完全没有看到他们的结果。

注意我“具有”记得用@Test来注释方法

下面是测试类代码：

package module.jakway.JournalEntry.test; 


import module.jakway.JournalEntry.Module_JournalEntry; 

import org.junit.After; 
import org.junit.AfterClass; 
import org.junit.Before; 
import org.junit.BeforeClass; 
import org.junit.Test; 

public class MainTest extends android.test.ActivityInstrumentationTestCase2<Module_JournalEntry> 
{ 

    public MainTest(Class activityClass) { 
     super("module.jakway.JournalEntry", Module_JournalEntry.class); 
     // TODO Auto-generated constructor stub 
    } 

    @BeforeClass 
    public static void setUpBeforeClass() throws Exception { 
    } 

    @AfterClass 
    public static void tearDownAfterClass() throws Exception { 
    } 

    @Before 
    public void setUp() throws Exception { 
     super.setUp(); 

     Module_JournalEntry journalentry = getActivity(); 

     assertTrue(true); 
    } 

    @After 
    public void tearDown() throws Exception { 
    } 

    @Test 
    public void myTestCase() 
    { 
     assertTrue(false); 
    } 

} 

项目我测试名为Module_JournalEntry与包module.jakway .JournalEntry和活动Module_JournalEntry.java

这里是控制台输出：

非常感谢！

Answer 1

Android的测试框架基于JUnit 3，它不使用注释，但反射和测试方法名称应包含测试前缀。

转到JUnit 3并从Eclipse运行测试，作为Run As -> Android JUnit Test或从命令行使用am instrument。

Answer 2

尝试修改此：

public MainTest(Class activityClass) { 
    super("module.jakway.JournalEntry", Module_JournalEntry.class); 
    // TODO Auto-generated constructor stub 
} 

要这样：

public MainTest() { 
    super("module.jakway.JournalEntry", Module_JournalEntry.class); 
    // TODO Auto-generated constructor stub 
} 

构造函数应该在这种情况下，没有参数。它写在Hello, Testing教程示例下的添加测试用例构造函数部分。

Answer 3

“Android的测试API支持JUnit 3中的代码风格，而不是JUnit 4中” - http://developer.android.com/tools/testing/testing_android.html

1.Update测试遵循的JUnit 3个标准

 

    //has to start with the word "test" for JUnit 3 to pick it up. 
    public void testMyCase() 
    { 
     assertTrue(false); 
    } 

2.取出任何JUnit 4个中引用从测试项目（右键单击项目 - >属性 - > Java构建路径 - >库（标签）
